By Renee Maltezou and Jonathan Saul ATHENS/LONDON (Reuters) -Rescuers pulled three more crew members and a security guard alive from the Red Sea on Thursday, maritime security sources said, a day after Houthi militants sank the Greek ship Eternity C and said they were holding some of the crew still missing.

Rescuers found four more crew members Thursday who went missing after Yemen's Houthi rebels sank a ship in the Red Sea as the United States alleged the group may “have kidnapped” others on board.

The Eternity C, a commodity carrier, sank Wednesday morning, two days after it came under attack, the European Union’s naval force in the area said in a statement.
